What accessories do I need for the sony rx10 v?

The RX10 V has a built-in lens, so you won't need to buy a separate one. The site doesn't have a list of accessories for this camera, so I can't name specific batteries, bags or chargers.

If you plan to shoot video, the Video guide explains why ND filters matter. In daylight, they let you keep a sensible shutter speed, around 1/50s at 25 frames a second, even with the lens open wide. Check the Sony RX10 V page for the lens and sensor details before you buy anything to go with it.
